Pond co-culture technology for crayfishes and yellow catfishes

Abstract

The invention relates to a pond co-culture technology for crayfishes and yellow catfishes. The technology is characterized by co-culturing crayfishes and yellow catfishes, which are a predating variety and a predated variety, in a same pond; the technology is a technology of preventing a floating expanded feed from floating out of a net cage by adhering a plastic film on the net cage. According to a technical scheme adopted by the pond co-culture technology for crayfishes and yellow catfishes, the technology comprises the steps of: I, separated culture of crayfishes and yellow catfishes in the net cage; II, pond condition and preparation; III, structure and placement of the net cage; IV, fry throwing and culture; and V, cultural management. The crayfishes and yellow catfishes, which are a predating variety and a predated variety, are co-cultured in the same pond, so that two high additional value brand-name and high-quality aquatic product varieties which cannot be output by virtue of a conventional technology can be output in one pond. Therefore, the cultural water level is reasonably utilized, and the economical benefit is improved. By adhering the plastic film on the net cage, the floating expanded feed is prevented from floating out of the net cage, so that the cultural cost is saved and lowered.

Description

Technical field [0001] The patent of the present invention involves the healthy breeding field of crayfish and belongs to the scope of agricultural technology. Background technique [0002] According to the applicant, crayfish and yellow catfish are very popular water products that are very popular in the market. Crayfish belongs to freshwater crustaceans and crawls at the bottom of the camp;Activity is a fierce carnivorous animal; therefore, crayfish and yellow catfish are predatory and predatory relationships. The two are cultivated in the same pond, and yellow catfish will eat crayfish.Therefore, farmers dare not cultivate these two aquatic products in the same pond and have never carried out this breeding model.However, the two requirements for water body water quality are the same. One living at the bottom of the water body crawling life, a parade in the middle of the water body, and a mixer in a pond can make full use of the water body space to achieve the purpose of increa...
